In a plant cell, which organelle carries out photosynthesis?
AThe mitochondrion
BThe central vacuole
CThe nucleolus
DThe chloroplast
Answer & Solution
Correct answer: D. The chloroplast
1. Photosynthesis uses carbon dioxide, water, and light energy to make glucose and oxygen.
2. Chloroplasts are the plant cell organelles that carry out this process.
3. They hold chlorophyll, the green pigment that captures the light energy.
4. Mitochondria burn glucose to make ATP; that is respiration, the trap in the mitochondrion option.
